2. Which of the words in the question above did you find in the video? List them
All words were mentioned in the video.
3. What was the embarrassing secret Newton was holding about gravity?
Newton didn’t know how gravity works.
4. The narrator presents some examples in the video. What happens in the first one? What happens to the sun and planets? Explain
In the first experiment, the sun disappears, and by Newton’s law, the planets would leave their orbits and fly off into space.
5. What happens in the second one? What happens to the sun and planets? Explain
In the second experiment, after the Sun disappears is creates a wave and when the wave reaches the planets, the planets leave their orbits and fly through the space.
6. Why was Newton’s idea of gravity incorrect for Einstein?
Because Newton thought that gravity could travel faster that light, but Einstein found out that nothings travel faster than light.
7. What is the final definition of gravity given in the video?
According to Einstein, it is curves and warps in the fabric of space-time.
8. What’s the name Einstein gave to it?
General Relativity.
9. What’s the difference between Newton’s gravity and Einstein’s gravity?
The difference between Newton’s gravity and Einstein’s gravity is that Newton said that gravity is force that acts on the planets, but Einstein said that gravity is an attractive force when there is an object in the space, and when the space is distorted is produced the gravity acceleration.
